Hello,
Groin lumps and armpit lump are swollen
lymph nodes.
Lymph nodes are small (1-2cm) and bean-shaped nodes.Lymphadenopathy (swollen lymph nodes) is usually caused by a viral or bacterial infection. Other causes include allergic reactions, arthritis, cancer, metabolic diseases, and an overactive thyroid (hyperthyroidism).
In sinusitis, the glands in the neck are most likely to swell—a common response to a cold or upper respiratory infection or allergies.
